What are the types of the QuestStep::quest_ and Quest::steps_ data
members? Based on your mapping, they should be pointers to objects
of some sort.

That would normally mean that QuestStep is treated as a value rather
than an object. What does the line that this error points to contain?
And in the future always show what the error points too -- I have no
way of knowing what it is!
